%X To obtain the higher range resolution Inverse Synthetic Aperture Radar (ISAR) image, a method by combining the bandwidth of the Linearly Modulated Stepped Frequency (LMSF) radar signal in frequency domain is discussed. The model of high speed moving targets is proposed. In order to estimate the target motion parameters accurately, the method employing envelop alignment and Doppler center estimation is provided to fit the track of moving target. Based on the characteristic of target echo in ISAR, the original method of Doppler center estimation is ameliorated to increase the motion parameter estimation precision. Finally, the processing scheme is proposed, and the simulation results show that the method is effective.
